Halfway Between 15 and 633

When you ask "What number is halfway between 15 and 633?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=633.

Halfway Between Line

To find the number halfway between 15 and 633, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 633 into our formula, we get:

(15 + 633)/2 = 324

Thus, the number halfway between 15 and 633 is 324.

To check that our answer is correct, we subtract 15 from 324 and subtract 324 from 633 and compare the two numbers:

324 - 15 = 309
633 - 324 = 309

As you can see, the halfway number is 309 higher than 15 and 309 lower than 633. Therefore, our halfway between answer of 324 above is correct.
